Python language server is installed but not found by Helix text editor
Problem description
I am using Helix text editor and am trying to add a Python language server (link) to it.
I installed Python 3 using the .exe from their official website. Then I executed these commands in order to install the Python language server:
C:\Users\ZIGLA> pip config set global.trusted-host "pypi.org files.pythonhosted.org pypi.python.org"
C:\Users\ZIGLA> pip install pip-system-certs
C:\Users\ZIGLA> python.exe -m pip install python-lsp-server
Setup succeeded but when I try running the pylsp command my system can't find it. Helix editor also can't detect it when I check its health:
C:\Users\ZIGLA> hx --health
Config file: C:\Users\ZIGLA\AppData\Roaming\helix\config.toml
Language file: C:\Users\ZIGLA\AppData\Roaming\helix\languages.toml

My attempt to solve the problem
First I checked where pip installed the Python language server:
C:\Users\ZIGLA> pip list -v

I see that Python language server was installed in the pylsp subfolder. However when I inspect this folder I can not see any executables. It looks like this is a python module:
C:\Users\ZIGLA> ls C:\Users\ZIGLA\AppData\Roaming\Python\Python311\site-packages\pylsp\

This plugin is needed by Helix editor. This is why I tried adding this path to the PATH enviromental variable. By opening my Powershell profile like this:
hx $PROFILE
And adding this line inside:
$ENV:PATH += ";C:\Users\ZIGLA\AppData\Roaming\Python\Python311\site-packages\pylsp"
I rebooted the terminal and I could see that path was appended at the end of the PATH:
C:\Users\ZIGLA> echo $ENV:PATH
C:\Program Files\PowerShell\7;C:\Program Files\Microsoft MPI\Bin\;C:\Program Files\Python311\Scripts\;C:\Program Files\Python311\;C:\Program Files\Microsoft SDKs\Azure\CLI2\wbin;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Windows\System32\OpenSSH\;C:\Program Files (x86)\Citrix\HDX\bin\;C:\Program Files\Citrix\HDX\bin\;C:\Program Files (x86)\Citrix\Workspace Environment Management Agent;C:\Program Files\PowerShell\7\;C:\Program Files\Microsoft VS Code\bin;C:\Program Files\Azure Data Studio\bin;C:\Program Files\Azure Dev CLI\;C:\Program Files\PuTTY\;C:\Program Files\nodejs\;C:\Program Files\Microsoft SQL Server\Client SDK\ODBC\170\Tools\Binn\;C:\Program Files\dotnet\;C:\Program Files (x86)\Microsoft SQL Server\160\Tools\Binn\;C:\Program Files\Microsoft SQL Server\160\Tools\Binn\;C:\Program Files\Microsoft SQL Server\160\DTS\Binn\;C:\Program Files (x86)\Microsoft SQL Server\160\DTS\Binn\;C:\Program Files\Microsoft SQL Server\150\Tools\Binn\;C:\Program Files\Meld\;C:\Users\ZIGLA\AppData\Local\Programs\Python\Python312\Scripts\;C:\Users\ZIGLA\AppData\Local\Programs\Python\Python312\;C:\Users\ZIGLA\AppData\Local\Programs\Python\Launcher\;C:\Users\ZIGLA\AppData\Local\Microsoft\WindowsApps;C:\Users\ZIGLA\AppData\Local\GitHubDesktop\bin;C:\Users\ZIGLA\.dotnet\tools;C:\Users\ZIGLA\AppData\Local\Programs\Git\cmd;C:\Users\ZIGLA\AppData\Local\Microsoft\WinGet\Links;;C:\Users\ZIGLA\AppData\Roaming\helix;C:\Users\ZIGLA\AppData\Roaming\omnisharp-win-x64;C:\Program Files\Meld;C:\Program Files\Windows Application Driver;C:\Program Files\Microsoft Visual Studio\2022\Enterprise\Common7\IDE;C:\Users\ZIGLA\AppData\Local\DeviceTestCenter\Tools;C:\Program Files (x86)\Microsoft SQL Server Management Studio 19\Common7\IDE;C:\Users\ZIGLA\AppData\Roaming\Python\Python311\site-packages\pylsp
However, symptoms remain. Helix can not detect pylsp when checking its health.

When I tried to uninstall the language server I found out where the pylsp.exe is located!
C:\Users\ZIGLA> python.exe -m pip uninstall python-lsp-server
Found existing installation: python-lsp-server 1.11.0
Uninstalling python-lsp-server-1.11.0:
Would remove:
c:\users\zigla\appdata\roaming\python\python311\scripts\pylsp.exe
c:\users\zigla\appdata\roaming\python\python311\site-packages\pylsp\*
c:\users\zigla\appdata\roaming\python\python311\site-packages\python_lsp_server-1.11.0.dist-info\*
I was adding the wrong path to PATH all along. When I added this line in my Powershell profile:
$ENV:PATH += ";C:\Users\ZIGLA\AppData\Roaming\Python\Python311\scripts"
Now everything works fine.
